Abstract

The Hall coefficient is measured in YBa $_{2}$ Cu $_{3}$ O $_{y}$ untwinned single crystals for a wide range of doping. We show that the Hall conductivity and the Hall angle of the {\it CuO $_{2}$ planes} in YBa $_{2}$ Cu $_{3}$ O $_{y}$ can be extracted from measurable transport properties regardless of the conduction of the Cu-O chains nor the in-plane anisotropy of the CuO $_{2}$ planes. The present analysis allows us to discuss the genuine Hall effect in the CuO $_{2}$ planes alone in YBa $_{2}$ Cu $_{3}$ O $_{y}$ without any complications due to the Cu-O chains.
